Description

Technical Field

[0001] The utility model relates to a cleaning device, in particular to a device for cleaning scale accumulation on a pressing head of a cigarette packing device. Background Art

[0002] During the leaf redrying process, a pre-pressing baler is often used to quantitatively load the finished tobacco leaves after redrying into finished tobacco boxes so that the processed tobacco leaves can be handed over, transported, stored, aged, and other requirements can be met.

[0003] like Figure 3 As shown, finished tobacco strips are transported at a constant speed by a bidirectional belt conveyor 100 to enter the pre-pressing and baling machine line A 200 or pre-pressing and baling machine line B 300 for baling. For example, the ram 400 of the pre-pressing and baling machine line A 200 rises to a preset position. After the carton 500 is in place, the material box 600 descends and feeding begins. When the set weight is reached, the belt of the bidirectional belt conveyor 100 reverses and feeds the material to the pre-pressing and baling machine line B 300. The ram 400 of the pre-pressing and baling machine line A 200 descends to compact the finished tobacco strips. The material box 600 rises, and the ram 400 also rises. This completes one baling cycle, and the next cycle begins, thereby achieving alternating operation of the rams of the two lines A and B.

[0004] In actual production, it is found that after the feeding of the material box 600 is completed, the pressure head 400 needs to pre-press the loose cigarette sheets in the material box 600. Since the cigarette sheets entering the material box 600 are piled up too high, when the pressure head 400 is pressed down quickly, the cigarette sheets are quickly squeezed, and the air between the cigarette sheets is compressed. The compressed gas needs to be discharged quickly. Although there are exhaust holes on the side of the material box 600, there is a certain gap between the pressure head 400 and the material box 600, and some air flows upward. During the discharge process, some cigarette sheets are brought into the groove at the top of the pressure head 400 by the upward air flow. Every time a box is loaded, the pressure head 400 is pressed down and raised once. Each time, some cigarette sheets are brought into the groove at the top by the rising air flow. During the repeated extension and contraction of the main oil cylinder, the tobacco slices accumulated on the upper part of the pressure head 400 are repeatedly squeezed, and the more they are squeezed, the harder they become, and finally the tobacco slices are tightly wrapped around the pressure head 400 and the piston rod, accumulating higher and higher. When they accumulate to a certain height, the tobacco slices are squeezed very hard again. When the pressure head 400 rises and approaches the upper position, the accumulated tobacco slices impact the cylinder cap of the oil cylinder, causing the entire pre-pressing baler to shake. The shaking causes the pre-pressing baler frame connecting bolts to loosen or the oil cylinder to leak oil; after a period of time, the pressure head 400 cannot reach the upper position when it rises, and the detection switch for detecting the upper position of the pressure head has no signal output. At this time, the pre-pressing baler must be stopped to deal with the tobacco slices accumulated on the upper part of the pressure head 400.

[0005] To deal with the accumulated tobacco flakes on top of the pressure head 400, the current method can only be to stop the machine regularly and manually use a crowbar to remove them. However, since the scale formed by the long-term crushing of the tobacco flakes is extremely solid, the manual cleaning method using a crowbar is inefficient and more likely to damage the pressure head 400, aggravating the scale accumulation on the pressure head 400.

[0022] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0023] The embodiment of the present utility model: Figure 1 and Figure 2 As shown, a device for cleaning dirt deposits on the pressure head of a cigarette packing device includes a hydraulic cylinder housing 1, a hydraulic cylinder 2 and a pressure head 3. The hydraulic cylinder 2 is fixedly arranged in the hydraulic cylinder housing 1, and the telescopic end of the hydraulic cylinder 2 is arranged vertically downward, and the telescopic end of the hydraulic cylinder 2 is fixedly connected to the top of the pressure head 3. An energy storage cylinder 4 and an air nozzle 5 are fixed on the outer wall of the hydraulic cylinder housing 1, and the energy storage cylinder 4 and the air nozzle 5 are connected in an air circuit.

[0024] The energy storage cylinder 4 stores gas. When the top of the pressure head 3 needs to be cleaned, the energy storage cylinder 4 simply supplies air to the air nozzle 5, which then blows out high-pressure gas to remove the tobacco flakes on the top of the pressure head 3, preventing them from accumulating and forming scale. This effectively solves the scale accumulation problem in the prior art and ensures normal and stable operation of the equipment.

[0025] In a specific embodiment, the energy storage cylinder 4 has an air inlet connector 6, a first air outlet connector 7, and a second air outlet connector 8. The air inlet connector 6 is connected to an air source via an air pipe. The air source can be a gas station, an air pump, or an air compressor.

[0026] Usually, cigarette factories are equipped with gas stations to provide high-pressure gas to all gas-using equipment. Of course, if there is no condition to set up a gas station, an air pump or air compressor can be set up to inflate the energy storage cylinder 4. The energy storage cylinder 4 plays the role of storing high-pressure gas.

[0027] Furthermore, a horizontal support plate 9 is fixedly provided on the outer wall of the hydraulic cylinder housing 1 , and the energy storage cylinder 4 is fixedly provided on the top of the horizontal support plate 9 .

[0028] Angle adjustment components are respectively provided on a set of opposite side walls of the hydraulic cylinder housing 1 , and air nozzles 5 are installed on both angle adjustment components.

[0029] In this embodiment, the energy storage cartridge 4 is mounted on the front outer wall of the hydraulic cylinder housing 1. An angle adjustment assembly is provided on both the left and right outer walls of the hydraulic cylinder housing 1. The air nozzle 5 on the angle adjustment assembly on the left wall is connected to a second air outlet connector 8 via an air pipe, while the air nozzle 5 on the angle adjustment assembly on the right wall is connected to a first air outlet connector 7 via an air pipe.

[0030] Specifically, the angle adjustment assembly includes a mounting bracket 10, a connecting plate 11 and a nozzle mounting bracket 12. The mounting bracket 10 is fixed to the outer wall of the hydraulic cylinder housing 1, and one end of the connecting plate 11 is rotatably connected to the end of the mounting bracket 10 by a first bolt 13. The nozzle mounting bracket 12 is fixed to the outer wall of the air nozzle 5, and the other end of the connecting plate 11 is rotatably connected to the nozzle mounting bracket 12 by a second bolt 14. A first hand-tightened nut 15 is installed on the first bolt 13, and a second hand-tightened nut 16 is installed on the second bolt 14.

[0031] By setting the angle adjustment component, the angle of the air nozzle 5 can be adjusted, and the cooperation between the connecting plate 11, the mounting bracket 10 and the nozzle mounting bracket 12 increases the angle adjustment range of the air nozzle 5, so that the air nozzle 5 can be adjusted to the optimal angle.

[0032] During adjustment, loosening the first hand-tightening nut 15 and the second hand-tightening nut 16 can realize the adjustment of the height and angle of the air nozzle 5. Only the first hand-tightening nut 15 and the second hand-tightening nut 16 need to be tightened after adjustment.

[0033] Furthermore, a PLC programmable controller 17 and two air intake solenoid valves 18 are provided on the outer wall of the hydraulic cylinder housing 1 , and the PLC programmable controller 17 is electrically connected to the two air intake solenoid valves 18 .

[0034] The two air inlet solenoid valves 18 are respectively installed on the air pipe connecting the first air outlet connector 7 and the left air nozzle 5, and on the air pipe connecting the second air outlet connector 8 and the right air nozzle 5. The opening and closing states of the air inlet solenoid valves 18 are controlled by the PLC programmable controller 17 to control whether the air nozzle 5 is to be ejected.

[0035] The PLC programmable controller 17 can be used to automatically control the puffing frequency and puffing time according to the different tobacco sheet accumulation conditions. The control programming can be written by those skilled in the art according to the needs. It is a conventional technical means and the specific programming method will not be repeated here.

[0036] Furthermore, the upper portion of the pressure head 3 is a frustum structure, and the side length of the pressure head 3 gradually increases from the upper portion to the bottom. A groove 19 is formed at the top of the pressure head 3, and the four side surfaces of the groove 19 are all inclined surfaces.

[0037] By designing the upper portion of the ram 3 as a frustum, when the ram 3 moves downward rapidly, even if airflow carries away tobacco leaves, the leaves can slide down along the side walls of the ram 3 and back into the bin, reducing the number of tobacco leaves entering the top groove 19. The four sides of the groove 19 are designed as inclined surfaces, so that when the air nozzle 5 ejects high-pressure gas, the tobacco leaves will slide smoothly out of the groove 19 along the inclined surfaces, preventing them from getting stuck in corners.

[0038] It should be noted that the problem of tobacco sheet backlog cannot be solved by removing the groove 19 on the top of the pressure head 3, because the groove 19 is designed to prevent oil leakage from the hydraulic cylinder 2. If the groove 19 is not provided, the hydraulic oil leaked from the hydraulic cylinder 2 will flow directly onto the tobacco sheets, causing the tobacco sheets to be contaminated and affecting product quality.

[0039] The working principle of the present invention is as follows: during operation, the PLC programmable controller 17 controls the opening frequency and opening time of the air intake solenoid valve 18 according to a preset program. When the air intake solenoid valve 18 is opened, the high-pressure gas in the energy storage cylinder 4 is ejected through the air pipe and the air intake solenoid valve 18 through the air nozzle 5. The air nozzle 5 is a commercially available product and can be purchased directly. The high-pressure gas ejected by the air nozzle 5 can blow out the cigarette sheets in the groove 19 to prevent the cigarette sheets from accumulating.

[0040] If the angle of the air nozzle 5 is not appropriate, the first hand-tightening nut 15 and the second hand-tightening nut 16 can be loosened, and the first hand-tightening nut 15 and the second hand-tightening nut 16 can be tightened after adjusting the height and angle of the air nozzle 5.

[0041] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
